.SH "NAME"
log2pcap \- Extract network traces from Samba log files
.SH "SYNOPSIS"
.HP \w'\ 'u
log2pcap [\-h] [\-q] [logfile] [pcap_file]
.SH "DESCRIPTION"
.PP
This tool is part of the
\fBsamba\fR(7)
suite\&.
.PP
log2pcap
reads in a samba log file and generates a pcap file (readable by most sniffers, such as ethereal or tcpdump) based on the packet dumps in the log file\&.
.PP
The log file must have a
\fIlog level\fR
of at least
\fB5\fR
to get the SMB header/parameters right,
\fB10\fR
to get the first 512 data bytes of the packet and
\fB50\fR
to get the whole packet\&.
.SH "OPTIONS"
.PP
\-h
.RS 4
If this parameter is specified the output file will be a hex dump, in a format that is readable by the
text2pcap
utility\&.
.RE
.PP
\-q
.RS 4
Be quiet\&. No warning messages about missing or incomplete data will be given\&.
.RE
.PP
logfile
.RS 4
Samba log file\&. log2pcap will try to read the log from stdin if the log file is not specified\&.
.RE
.PP
pcap_file
.RS 4
Name of the output file to write the pcap (or hexdump) data to\&. If this argument is not specified, output data will be written to stdout\&.
.RE
.PP
\-?|\-\-help
.RS 4
Print a summary of command line options\&.
.RE
.SH "EXAMPLES"
.PP
Extract all network traffic from all samba log files:
.PP
.if n \{\
.RS 4
.\}
.nf
			$ log2pcap < /var/log/* > trace\&.pcap
	
.fi
.if n \{\
.RE
.\}
.PP
Convert to pcap using text2pcap:
.PP
.if n \{\
.RS 4
.\}
.nf
	$ log2pcap \-h samba\&.log | text2pcap \-T 139,139 \- trace\&.pcap
	
.fi
.if n \{\
.RE
.\}
.SH "VERSION"
.PP
This man page is part of version 4\&.21\&.2 of the Samba suite\&.
.SH "BUGS"
.PP
Only SMB data is extracted from the samba logs, no LDAP, NetBIOS lookup or other data\&.
.PP
The generated TCP and IP headers don\*(Aqt contain a valid checksum\&.
.SH "SEE ALSO"

\fBethereal\fR(1)
.SH "AUTHOR"
.PP
The original Samba software and related utilities were created by Andrew Tridgell\&. Samba is now developed by the Samba Team as an Open Source project similar to the way the Linux kernel is developed\&.

This manpage was written by Jelmer Vernooij\&.
